经尿道电切术治疗高危多发性非肌层浸润性膀胱癌（附21例报告）

目的探讨经尿道电切术治疗高危多发性非肌层浸润性膀胱癌的方法和疗效。方法对21例高危多发性非肌层浸润性膀胱癌患者行经尿道电切术治疗。结果19例一次手术将肿瘤完全切除，2例由于肿瘤数目多分两次切除。术后21例患者获得随访，随访时间为1-14年。2例患者死于其他疾病，余19例均无瘤存活。6例复发，复发率为28.6％。膀胱挛缩2例（膀胱容量小于150ml），膀胱壁增厚4例。结论经尿道电切术治疗高危多发性非肌层浸润性膀胱癌安全性高，并发症少，疗效确切，且没有增加肿瘤复发率。

Transurethral resection of high-risk multiple non-muscle invusive bladder tumor： report of 21 cases

Objective To determine the safety and efficacy of transurethral resection of high-risk multiple non-muscle invasive bladder tumor. Methods Twenty-one high-risk patients with non-muscle invasive bladder tumor undergone transurethral resection were reviewed retrospectively. Results All of the cases were followed up from 1 year to 14 years. Of them,19 were alive without tumor,2 died of other diseases. The overall recurrent rate was 28.6%（6/21）. Of the 21 patients,2 were with contracted bladder（capacity of less than 150 ml）, 4 were with thickened bladderwall. Conclusions Transurethral resection of high risk multiple non-muscle invasive bladder tumor is effective and safe,and may not increase the tumor recurrence rate.
